Abstract

The Duffy blood group antigen is a serpentine protein with seven transmembrane domains that is not coupled to G-proteins or other known intracellular effectors. In addition to erythrocytes, it is also expressed in endothelial cells and neurons. In recent years the Duffy antigen has received much attention because of its diverse roles in health and disease. These include its functions as a docking receptor for the invasion of human erythrocytes by the malaria parasite Plasmodium vivax. In addition, the Duffy antigen is a binding protein for multiple inflammatory chemokines. Its expression allows erythrocytes to regulate intravascular levels of chemokines. It has also been shown recently that the Duffy antigen plays an important role in endothelial cells by facilitating chemokine transcytosis and presentation. Given these diverse functions of the Duffy antigen, this short review presents detailed methods that can be used to investigate each of these potential roles of this multifaceted protein.
